CTC vs Gross vs Net: CTC includes your employer's PF contribution. Gross is CTC minus Employer PF. Net (In-Hand) is Gross minus your deductions (Tax, Employee PF, Professional Tax).
Tax Estimation (New Regime): This calculator estimates TDS using the default New Tax Regime, including the ₹50,000 standard deduction and applicable tax rebate under section 87A for incomes up to ₹7 Lakhs.
EPF Structure: By default, 12% of your Basic Salary is deducted as your EPF share, and an equal 12% is contributed by your employer (which is part of your CTC).
